Opinions of 15" sub.

I have a audio pipe apsm 1300 amp, stock electrical, with knukeptz kolusus flex 4 gauge wiring. Need opinion on a 15" sub that would match the amp. Price under $250. So far I am considering an Obsidian 15" or a sundown sa 15".

Re: Opinions of 15" sub.

i might get a bigger encloser. I was thinking about going with 2 sa 15's and doing a big three on my car. but id need some component speakers and that puts me way over my budget. Im leaning towards the obsidian.
